Blueberries are small juicy fruits from the Ericaceae family, characterized by their attractive dark blue or red color and a flavor that combines sweetness with a slight tartness. Originating from cold, mountainous climates like Asturias, their ideal season for consumption extends from March to September. For every 100 grams, blueberries provide an energy value of 33 kcal, very low in fat at only 0.6 g, and contain a good amount of water (87.8 g) and fiber (4.9 g), making them a healthy snack. Their versatility in the kitchen is unmatched; they can be used in a variety of desserts, salads, or incorporated into recipes like mousse with creamy cheese. To maintain their freshness, it is recommended to store them in the fridge, where they can last 3 to 4 days. If you need to store them for longer, you can choose to freeze them, ensuring that you always have blueberries available. Remember not to wash them until just before consumption to preserve their quality.
